What I would like to do is install an external 2TB hard drive to my AppleTV2, through a bunch of media on it, and then use it to both watch on the ATV2 and ATV1 that the external hard drive is connected to. It would be on a wired gigabit network.
Does the AppleTV2 need to be jailbroken and have aTV Flash installed on it for this to work? Or can I simply stream from my AppleTV1 (aTV Flash Installed) to a stock AppleTV2?
